Title: Method for improving the steam splits in a multiple steam injection process
Inventor: STOWE GEORGE R III
IPC: C09K8/594
Filed: 1990-07-12
Abstract: ABSTRACT            A method is disclosed for enhancing the uniformity of steam distribution in a multiple steam injection system having a steam generator, a steam header, a primary steam line connecting the generator to the header, and a plurality of secondary steam lines connecting the header to a plurality of steam injection wells.  The method comprises injecting a surfactant into the primary steam line, and mixing the surfactant and steam sufficiently so that the surfactant and the steam enter the header as an emulsion.  The concentration of the surfactant in the emulsion should be above the critical micelle concentration, so that the surfactant will foam.  Preferably, the surfactant is injected into the primary steam line within seventy-five feet of the steam header.  More preferably, the surfactant is injected into the primary steam line within fifty feet of the steam header.  Still more preferably, the surfactant is injected into the primary steam line within twenty-five feet of the steam header.  In one embodiment, at least one of the secondary steam lines is split and additional surfactant is added and mixed prior to said split.

IPC: G10L19/083
Filed: 1990-10-16
Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a novel speech coding system which recursively executes a filter-applied "Toeplitz characteristic" by causing a drive signal (i.e., an excitation signal) to be converted into a "Toeplitz matrix" when detecting a pitch period in which distortion of the input vector and the vector subsequent to the application of filter-applied computation to the drive signal vector in the pitch forecast called either "closed loop" or "compatible code book" is minimized.  The vector quantization method substantially making up the speech coding system of the invention is characteristically used by the system.

Title: Multiple motion centrifuge
IPC: B04B9/00
Filed: 1990-11-01
Abstract: A centrifuge device is provided which may impart selectively controlled centrifugal force to samples (30,32) under consideration, or a shaking or agitation movement to the samples, as required. A feature of the invention is the use of two roller clutches (18,20) on the single drive shaft (14) of the device so that a selective movement may be imparted to the samples (30,32) through the same drive by utilizing a locking mechanism to provide rotation from the shaft in opposite directions. Rotation in one direction causes the imposition of centrifugal force through one clutch (20), while rotation in the opposite direction causes rotation through the second clutch (18) and the imposition of agitation. In that direction, the sample support mechanism is moved vertically, controlled by a cylinder cam (76). A further feature of the invention is selective agitation movement and selective degree of agitation through selection of a particular cam profile (70). <IMAGE>

The preferred apparatus and method thereafter perform a non-linear image processing, either by an iterative side lobe subtraction signal processing procedure to remove signal noise and/or by an iterative hybrid mapping signal processing procedure.  The resulting data map yields a high resolution image of the selected target with more data and less noise.  Signal processing to show motion or target object changes after noise reduction is also disclosed.  In a preferred embodiment, the apparatus and method is employed as a clinical diagnostic tool for generating non-traumatic, high resolution imaging of bodily tissue.

Title: Liquid level detection apparatus and method thereof
Inventor: JIN DONG Z
IPC: G01F23/26
Filed: 1991-02-28
Abstract: ABSTRACT             Disclosed is a liquid level detection apparatus using the Archimedean principle suited for the measurement of the level of a liquid, in particular a high temperature molten metal.      The liquid level detection apparatus is comprised of a probe (3) which inserted in a molten metal (2) and receives a buoyancy corresponding to the level of the liquid, an arm (4) which is supports the probe at one end, a support (7) which supports the arm, a force detector (8) which is provided under the other end of the arm and detects the buoyancy received by the probe through the arm, and a signal processing means (13) which performs operational processing on the electrical output signals of the force detector and finds the level corresponding to the output.  In accordance with the Archimedean principle, if the specific gravity of the liquid is considered constant, them the change in the volume of the probe in the solution, that is, the change in the depth of entry, is proportional to the change in the buoyancy and, using this, the force is detected and operational processing performed to detect the liquid level.
